Netaji Subhas Chandra Bose was active in India's Independence movement. He personally believed in establishing an entirely independent socialist state, and was aggressively anti-partition.
He garnered popular support for his use of military force to liberate India. But at the similar time, he also showed his support for the Axis Powers in WWII when the Alliance were attempting to liberate the sub-continent, which attracted much criticism.
His mysterious disappearance has also captured popular imagination for decades.
Recently, there has been a rise in his popularity as his family and others have started to present his legacy and ideas about military use, socialism, anti-partition ideology, and strong mindedness as desirable and appropriate for the present times.
